The results of the pressure test of the waterline have been submitted to the record.

Mr. Kirby also noted that a Title letter has been provided explaining that the title and records for the property do not provide evidence of any restriction on the site or ownership by the National Park Service. Ms. Ladd thanked the applicant for making substantial changes to the plan. Mr. Hnatko agreed the removal of three units made positive changes to the plans. Mr. Whelan expressed that he appreciates less trees being proposed for removal. Mr. Olivier stated that the National Park Service’s (NPS) letter stated they hold a jurisdictional oversight role under statute and he asked for further comments from NPS. Ms. Ladd noted that boulders or fences should be installed rather than Feno bounds to ensure residents understand not to disturb the resource areas. Ms. Margie Brown, Integrated Resources Program Manager at Minuteman National Historical Park, stated the National Park Service holds a legal interest in the property as recorded as part of public law 102-488. Ms. Brown stated that the parcel is within the administrative boundary of the National Park Service and they hold a legal interest in the property remaining as one-family. Mr. Olivier asked if Ms. Brown could elaborate on the legal interest in the property remaining as a single-family dwelling. Ms. Brown stated that there is a thirty-year clause and that the administrative boundary has not changed and could only be changed through Congress. Ms. Brown stated that this information is included in a letter previously submitted to the record from the National Park Superintendent. Ms. Janet Lane, 21 Hayward Ave, stated she has concerns regarding the proposed plantings and asked that visual screening be included on the portion of the lot bordering 7 Amherst St. Ms. Lane also asked that proposed plantings be revised to include more resilient plantings. Ms. Lin Jensen, 133 Reed Street, stated that all of the multi-dwelling projects proposed in town require the removal of many trees and expressed concern for the environmental loss of these trees. Ms. Jensen also expressed concern for chemicals used for pest control purposes. Ms. Ladd stated that any proposed trails for ACROSS Lexington on the site should be unimproved single path trails and that no official trail should be included under any powerlines. Ms. Linda Adler, 33A Woodpark Circle, stated that the proposed garden would be visible from their property and expressed concern for the mitigation of water runoff into the wetlands and how it would impact their property. Ms. Adler also asked about the height of the retaining wall and if there would be screening plantings along the retaining wall. Mr. Fred Russell, project engineer, stated that the retaining wall would be no higher than four feet in height. Mr. Kirby noted that the applicant will keep screening in mind through their revisions to the planting plan. Ms. Brown stated that the zoning regulations for multi-family housing include preservation and minimized impacts on natural features and resource areas. Mr. Kirby stated that the proposal has very minimal impact on sensitive areas on site within the revised concept plan.

Mr. Sami stated that he received an Order of Conditions in 2022 and in 2024 there was unauthorized vegetation removal and installation of ground cover onsite. Mr. Sami also stated that the property has a history of wetland disturbance, predating all wetland regulations. Mr. Sami also stated a proposal has been submitted proposing the establishment of restoring the 25-foot buffer zone to native plantings. Ms. Ladd stated that the vegetation removed in the 25-foot buffer zone appears to have been native species based on aerials of the site. Ms. Ladd also noted that the number of shrubs proposed for planting should be increased to mitigate for what has been removed. Ms. Herald presented the proposed restoration planting list. Ms. Ladd suggested that the highbush blueberry be removed from the list, to increase the total number of shrub species to five and increase the total number of tree species to five. Mr. Whelan suggested adding native alder to the list of trees. Ms. Ladd asked Ms. Herald for updated information regarding the soil testing as well. Ms. Herald noted that she has not been able to return to the site yet but provided the history of the site’s soil disturbance. The Commission discussed including Feno bounds surrounding the restoration area. Ms. Herald stated that the plan can be revised to have Feno bounds every 15 feet rather than the originally proposed 30 feet. Ms. Mullins suggested large boulders along the 25-foot buffer zone. Ms. Herald asked if a post and rail fence would be acceptable. Ms. Ladd noted that post and rail fences tend to rot and are less permanent than boulders or Feno markers. Ms. Ladd stated that the boulders can be placed between the Feno markers. Mr. Sami asked if the Commission would consider this project as an Amendment to the 2022 Notice of Intent or if this project should be pursued still through this new Notice of Intent filing. Mr. Hamilton noted that an Amendment to the Order of Conditions would require a new filing and re-opening that hearing. On a motion by Mr. Whelan and seconded by Mr. Hnatko, the Commission voted 7-0 by roll call vote to continue the hearing to 6/23/2026, at the applicant’s request.
